Investigation of chemical enhanced oil recovery core flooding processes with special focus on rock-fluid interactions

Hendrik Födisch
Chemical Enhanced Oil Recovery (cEOR) methods have been established since several decades. Despite the continuous research and development challenging reservoir with temperature above 80°C and salinities of more than 100 g/l cannot be targeted commercially yet. During the course of this work these high salinity and high temperature cEOR processes were investigated. It was discovered that combinations of anionic, cationic and non-ionic surfactant systems can be used under these conditions. The focus during the initial...
